NongYunHui main stadium heavy steel fabrication main body project completionFrom the 7th national NongYunHui main stadium projects department learned that NongYunHui main stadium main body construction has been completed. At present, has entered a stage of floating roof installation and curtain wall masonry construction.

On December 9, the reporter sees in the main stadium construction site, the spectacular stadium stands proudly, all show the majestic of nanyang new landmark. On the top of the dozens of meters high, the workers are installing metal floating roof "in extremely good fortune". Buildings around, the workers in the dismantled scaffold, some on masonry walls.

According to Huang Wei, main stadium are huge, with a total construction area of 420000 square meters, the cost of steel 9000 tons, 50000 cubic metres of concrete; Building structure is complicated, only, there are more than 800 posts and beams hundreds of root, plus top mounted with floating roof, node location, more complex support system; The overall appearance is oval, streamline modelling, more increased the difficulty of construction. To solve these problems, construction of prestressed steel strand, prestressed steel reinforced concrete adopted slow coagulation, such as new technology. Among them, in more than 800 columns, has 148 slow condensation of prestressed steel strand is adopted new technology. Each strands to the limit of the tolerance of 26 tons, design carrying 19 tons, 1 the columns up to use the 24 root steel strand, greatly improving the pillar support ability.

Huang Wei said: "the principal part of the project after completion, is a large quantity, in the late time is more urgent. We will continue to carry forward successive style, stepping up construction, to hand in a satisfactory answer on time to the people in the city."
